1. The following are body mass index (BMI) scores measured in 12 patients who are free of diabetes and participating in a study of risk factors for obesity. Body mass index is measured as the ratio of weight in kilograms to height in meters squared.

25 27 31 33 26 28 38 41 24 32 35 40

What is Q1 and Q3?

Median = 24 25 26*27 28 31^32 33 35*38 40 41 theres 12 data; (12+1)/2 = 6.5, the middle number is 6.5 values from each end or (31+32)/2 = 31.5 The Median is 31.5. a. Q1 = (6+1)/2 .5, number from the left or (26+27)/2= 26.5 b. Q3 = (6+1)/2 .5, number from the right or = (35+38)/2= 36.5

Is this correct?
